ASTEC™ FRP Active Anchors

Ground anchors ASTEC Active Anchors

FRP post-tensioned anchoring solution

An Active Anchors is post-tensioned from the external face of the ground immediately after installation, and is usually designed to help prevent deformation of the ground or retained structure. It has a free length and a bonded length.

A typical application for Active Anchors is anchoring of retaining walls during excavation works. To prevent the wall from the smallest displacement, the anchor is pre-loaded.

ASTEC Active Anchors is made of composite material, which is by nature cut-able. The tendons can be excavated by any standard equipment, therefore anchor removal is never required.


About our ASTEC FRP anchors

  • For temporary applications, take advantage of the cuttable nature of FRP bars. At the end of the project, anchor doesn’t need to be removed from the ground, as it can be cut by standard earth moving equipment or Tunnel Boring Machines (subway projects).
  • For permanent applications, the full resistance of the FRP anchor to corrosion will guarantee optimal performance over the years. No additional corrosion protection accessories required.
  • Multi-tendon: from one to 14 tendon. Each FRP tendons is spliced to a standard PT strand in sleeve (no friction for the free length) which can be tensioned with standard jack equipment.
  • Ultimate load capacity up to 3,500 tons.
